The Chelsea 871 Series Power Take-Off, part number 871XFFJP-D3BC or 871XFFJPD3BC, is a 10-bolt hydraulic PowerShift PTO designed for demanding continuous-duty applications. The 871 Series carries a series-rated torque capacity up to 670 lb-ft (908 N-m) with no derating required for continuous operation. Nine speed ratios and thirteen output options cover a wide range of installation requirements. The ductile iron bearing cap is 117% stronger than gray iron, and an O-ring sealing configuration between the housing and bearing cap improves clamp load while reducing the effects of engine vibration. The compact housing profile limits clearance conflicts in tight installations. Optional features include Wet Spline pump flange for extended PTO and pump shaft life, SmartStart to reduce shock load at start-up, Quiet Gear input, and Electronic Overspeed Control (EOC) to protect driven equipment. The 871 Series is engineered for Allison transmissions. Call us to confirm the correct configuration for your application.
